摘要
Compared to conventional bulky spectropolarimeters,computational spectropolarimeters which reconstruct light-field information such as polarization and spectrum in a compact form factor,are critical equipment enabling new applications.The key component of a computational spectropolarimeter is a tunable light-field modulator,in which liquid crystal-based device is a promising candidate.By varying the applied voltage,the tunable liquid crystal metasurface can modulate the phase and spectral information of the incident light,and after a few trials,this important information can be decoded mathematically.Such a novel approach paves the foundation for developing compact and low-cost spectropolarimetric imaging devices with widespread applications in biomedical imaging,remote sensing,and optical communications.
